PURPOSE: A manufacturing method of methane from synthetic gas is provided to minimize equipment cost due to process simplification, thereby effectively manufacturing methane by an insulative reactor. CONSTITUTION: A manufacturing method of methane comprises a step of forming a mixed gas by adding steam into a synthetic gas including carbon monoxide and hydrogen as main ingredients; a step of supplying the mixed gas to an isothermal reactor; and a step of synthesizing methane by transferring gas with high methane content to insulative reactors (7-9). 10-50 vol% of steam is added based on the total volume of the synthetic gas and steam. The isothermal reactor supplies saturated water, and maintains temperature of an isothermal reactor. |
